Question

Note the mechanism of absorption (passive or active transport) of the following food breakdown products, and indicate by a check mark whether the absorption would result in their movement into the blood capillaries of the lymphatic capillaries (lacteals).
Substance Mechanism of absorption Blood Lymph
Monosaccharides
Fatty acids and glycerol
Amino acids
Water
Ca2+ , Na+ , Ca2+

Answer 1

Answer:

The absorption of monosaccharides takes place via facilitated and cotransport mechanism and is transported through blood capillaries present in the villi.  

The absorption of glycerol and fatty acids takes place through diffusion and the majority of them are transported via lymph capillaries, while some are transported through blood capillaries.  

The absorption of amino acids takes place via a cotransport mechanism with sodium ions and is transported through blood capillaries.  

The absorption of water takes place by the process of osmosis via diffusion and is transported with the help of blood capillaries.  

The absorption of calcium and sodium ions takes place via an active transport mechanism, while the absorption of chlorine takes place via the process of diffusion. The transportation of all these ions takes place with the help of blood capillaries.
